Who we are

Company history

Since 1980, the formerly named “PMM”  is the Italian leader for design, manufacture and market of measuring equipments in the Radio Frequency field in general, with particular evidence in the EMC (Electro Magnetic Compatibility) applications. Company’s leading position was suddenly achieved thanks to an unsurpassed vocation to metrology realized since the early days in a complete set of test facilities, including an Open Area Test Site and a fully anechoic chamber, perfectly equipped to perform state-of-the art EMC and RF test and calibration.

In 1981 PMM was accredited as Calibration Center, SIT number 08/E under official Italian calibration scheme, for RF power, electric field, frequency and voltages.

In 1985 PMM has been inserted in the authorized Laboratory list by the Italian Ministry for Scientific and Technologic Research (LIGURIA – II list N. 159); based on rules stated on italian law # 46/1982, to put into practice and coordinate the initiatives in support of scientific and technologic research.

Since 1991 PMM is involved in standardization activities, being present in international and Italian National Committees.
